The stop 28 is mortised and the latter in connection with the inner face of a side i5 forms a groove 24 extending lengthwise with respect to stop 23. The inner face of each side of the frame H5 at its lengthwise center, is provided with a lengthwise extending groove 25 for the'reception of a parting bead which, in connection with the stops I9, 29, provide a pair of runways 26, 26 for upper and lower slides to be each other.

referred to.

In Figures 1, 6, 8 and 9 the parting bead is designated 21. In Figure 13 the parting bead is designated 28.

The parting bead 21 is of cruciform contour which provides it with a pair of endwise aligning outer and inner central parts 29, 39 respectively and a pair of inner endwise aligning side parts 3|, 32 disposed at right angles to parts 29, 3|]. The said several parts of the head 21 merge into The part 29 is formed with a plurality of spaced sockets 33, only one shown, which open at the outer end thereof. The part 39 is formed with a plurality of spaced endwise opposed rectangular pockets 34, only one shown,

- verse threaded bores 35, only one shown. The

bores 35 extend from the sockets 35 to the sockets -moves with the said slides.

33. Arranged within each pocket 34 is a resiliently bead controlling element 31 of the laminated bow-shaped spring type, connected, as at 38, to bead 21. The elements 31 function to force the parting bead 21 outwardly from a frame 5 side l5, as shown in Figures 8 and 9. The elements 31 permanently bear against the base of groove 25 in frame side |5. A tensioning means is provided for each element 31 consisting of a threaded bolt 39 extending from socket 33 to beyond socket 35 and bearing against element 31. The bolt 39 has threaded engagement with the wall of a bore 35 and also with a polygonal shaped nut 49 seated in socket 35. The outer end of bolt 39 is grooved, as at 4|, for the reception of a suitable tool to adjust bolt 39. Seated upon the parts 29, 3| and 32 of the parting bead 21 is a weatherstrip and facing member 42 in the form of a cap having a plurality of spaced openings 43 registering with the sockets 33. The member 42 abuts throughout the outer edges of the parts 29, 3| and 33, a portion of the side faces of part 29 and a portion of the outer side faces of parts 3|, 32. The member 42 has portions 43 which are spaced from the points of mergence of the outer side faces of parts 3| 32 and the side faces of part 29. Each side stile 44 of the upper sash 2| is cut out at its upper end, as at 44'. Within the cutout is arranged a bearing plate 45 anchored by the holdfast means 46 to stiler44. Each side stile 44 of sash 2| is formed with a pocket 45 which opens into the cutout 44' near the upper end of the latter. The plate 45 has an opening 41 com municating with pocket 46. Arranged in the cutout 44' and positioned against plate 45 is a pivoted block or member 48 provided on its outer face at one side thereof with a flange 48 forming a guide for the stile when the sash 2| is positioned to associate with the frame l6. Countersunk in and extending through block 48, as well 4]) as loosely extending through opening 41 into pocket 46' is the pivot 49 for block 48. The inner end of pivot 49 carries a nut 50, and interposed between the latter and plate 45, as well as sur- M rounding pivot 49 is a resilient split controlling 65 washer 5| acting to maintain the plate and block in abutting relation. The plate and block 48 have the major portion of the length of their upper ends aligning. The outer corners at the upper ends of plate 45 and block 48 are cut out as at 50 52, 53 respectively (Figure 11). The cutout 52 is of greater depth than cutout 53. The cut out corners of the plate 45 and block 48 provide a keeper for maintaining a sash suspension or balance arm, to be referred to, in inactive or latched 55 position. There is associated with each side stile of the upper sash a vertically movable slide 54 of less length than that of the height of frame l6 and of a length substantially corresponding to that ofthe upper sash. The upper sash bodily These latter are of like construction and ride against the outer side walls of the runways 26, the cap member 42 of parting bead 21 and a Weatherstrip 8| to be hereinafter referred to. Each slide 54 includes a sash suspension or balance arm 55, an angle bar 56 having an inner and an outer flange 51, 58 disposed at right angles to each other and with the flange 58 disposed inwardly at right angles to the outer end of flange 51, a resilient weatherstrip member 59 abutting and extending inwardly at right angles to the free edge of flange 51, abutting the outer side face of flange 51, abutting against the front face of flange 58, extending from flange 58 to flange 48', bearing against the 7 is of the same width as that of arm 55.

block 48 and cap member 42 and having an overlapping portion 60 to provide a split loop 6|. The portion 68 is arranged against and is suitably connected to the sash Weight cord 62. A pivot 53 is provided for the upper end of arm 55 and which secures flange 58 and member 59 together and with member 59 positioned against arm 55. The arm 55, at its lower end, is connected to a side stile of sash 2|, as at 63. The upper end of arm 55 is formed with a latching means, as at 63" (Figure 4), which coacts with the keeper means formed by the cutouts 52, 53 for latching the arm 55 in inactive position. The slide includes a combined filler and keeper strip 64 which The strip 64 is secured to the outer face of the slide 54 between its transverse median and lower end of the latter. The strip 64 in proximity to its lower end is formedwith an opening 65 for the reception of a latching member 56 carried by a side stile of sash 2| for latching the latter and slide in opposed relation. Each side stile of sash 2|, at the lower portion thereof, has secured thereto a filler strip 81 of the same width as that of strip 64. The upper end edge of the latter is concave and the lower end edge convex. The lower end edge of arm 55 is convex. The upper end of strip 61 is concave. When arm 55 and window 2| are latched, the lower end of arm 55 seats in the upper end of strip 84 and the lower end of the latter seats in the upper end of strip 61. The arm 55, strip 64 and strip 81 are of the same thickness and width.

With respect to the lower sash 22, the slides 58 therefor and the parts coacting With the slides 58 are substantially of the same construction as that set forth with respect to slides 54 and the parts coacting with the latter. The side stiles of sash 22 are designated 89 and the cutouts 59 thereof which correspond in form to the cutouts 44' are arranged at the lower ends of the stiles 69. The bearing plates 18, pockets H, pivot blocks or members 12, cutouts 52, 53 on plates 10 and members 12 respectively, balance arms 13, with a slight difference to be referred to, angle bars 14, flanges 14' on blocks 12, members 15, strips 16 with a slight difference to be referred to and strips ll of the slides 88 correspond in construction to, but are reversed with respect to the plates 45, pockets 45, members 48, cutouts 52, 53, arms 55, angle bars 56, flanges 48', members 59, strips 54 and 85 respectively employed in connection with the slides 54 or the upper sash. The pivots l8, l8 and 19 employed in connection with the lower slides and lower sash correspond to and are for the same purpose as the pivots 63, 63 and 49 respectively employed in connection with the upper sash and upper slides. Latching members 85' corresponding to and functioning similar to the latching members 68 in upper sash are carried by the side stiles of the lower sashes 22, but the members 88 engage in openings 85' in the balance arms 13 in lieu of engaging in the strips ll. The slides 68 travel against the outer side Walls of runway 26 the cap 42 of bead 2'! and the Weatherstrip 8| to be referred to.

rranged within the runways 26, 25' are oppositely disposed resilient weathers-trips 8i 8 l having flat side portions 82, 83 respectively which extend in the grooves 23, 24 respectively. The portions 82, 83 of the strips 8|, 8] are anchored to a frame side 15 by the holdfast means 84. The strips 8|, 8| are formed with curved parts 85, 86 respectively providing split loops 81, 88 respectively which extend into the loop portions of the strips or members 15, 42 respectively whereby the slides of the sashes are slidably, resiliently and frictionally latched to the strips 8|, 8!. The members 15, 42 coact with the strips 8|, 8! respectively for frictionally latching the slide structures in non-adjusted position, and for frictionally latching said structures suspendingly in adjusted position when the sashes are nonadjusted or angularly adjusted or turned inside out.

In the modified form shown in Figure 13 the parting bead 28 is not of cruciform contour and it consists of an elongated sectional bar 81 of rectangular cross section having a cap member 88 secured against its outer edge. The member 88 has side portions 89 provided with outwardly directed flanges 98 at their inner ends. The flanges 90 are engaged by resilient elements 8! normally tending to force the parting bead 28 outwardly with respect to a frame side I5. The flanges 9O bear against the looped portion of the members 15, 42. The elements 9| are employed in lieu of the elements 31. Otherwise than that as stated the form shown in Figure 13 is the same construction as that shown in Figures 6 and 8.

With reference to Figure 14, it sets forth a modified form of connection between a suspension or balance arm and a sash for allowing the sash to be tilted at the top a certain'distance without raising vertically from the sill. The showing is as applied to a lower sash. The latter has mortised and secured in a side stile a plate 82 carrying a detachable headed member 93 for slidably and pivotally connecting the arm, indicated at 94,'to the sash. The arm is formed with a countersunk slot 95 for member 93.

The members 8|, 8| extend from the upper end of the window frame to the sill l8. The members 42, 15 correspond in length to the height of the sashes. The members 8|, 8i also constitute guides for the slides. The blocks 48, 12 provide guides for the sashes on the vertical movement of the latter, as they slide against the parting beads and arrest the inward shifting of the sashes.

The invention is also applicable to non-vertically movable upper and lower sashes to permit of the angularly adjusting of such sashes without vertically moving them and this may be accomplished by blocking the movement of the upper slides and lower slides with respect to the sides of the window frame. With respect to the angularly adjusting of a sash without vertically moving the latter, one example thereof is shown in Figures 18 and 19 of the drawings, and in this connection it will be stated that each side 96, only one shown of a window frame 91 is formed with a pair of spaced parallel stops 98, 99 which in connection with a window frame side 96 provides a groove I05. The grooves I88 extend from the frame top llll to the sill I82. Within each groove is arranged a structure I03 corresponding to and embodying the elements of a slide 54 or 68, depending as to whether the ner as sash 2i is connected to slide 54. It is to be understood that if the sash is to be swung outwardly from its bottom it will be provided with the same arrangement of elements as the sash 22 and that, it is to be connected to the structure I03 in the same manner as sash 22 is connected to slide 68. In Figure 19 a spring I05 corresponding to spring 9| Figure 13 is shown and also a Weatherstrip I06 corresponding to member 8|.

The bearing plates and the pivot blocks may be termed latching plates. The strips and balance arms coact to provide a weather tight joint between the side stiles and slides. The members 59, 15 coact with the members 8|, 8| to provide a weather tight joint for the slides. The angular adjusting of the sashes is not accomplished by the movement of the slides as in my Patent No. 1,928,543. The slides remain stationary during the angular adjusting of the sashes and are only moved vertically when the sashes are moved vertically, as in their normal position or when p a sash is completely reversed and one Wishes to reach the outside surface from the floor level which eliminates using a stool or ladder to reach the upper sash.

The slides and balance arms and latching members coacting carry the sashes in normal Vertical movement.

The slides and balance arms alone carry the sashes in vertical movement when sashes are turned inside out and the balance arms are nearly parallel to the slides with the pivot blocks slid to the bottom of the upper sash slide for the upper sash or top of the lower sash slide for the lower sash shown in Figure 16.

The slides become stationary elements during the angular adjustments of the sashes and are only used in combination with the balance arms and pivot blocks as means for attaching the top ends of balance arms pivotally; as means for the pivot blocks to slide on; and as means in combination with the side of the parting bead to form a vertical trackway therebetween in which the pivot block flanges may travel vertically and arrest the rotation of the pivot block and also hold the pivoted ends of the sashes in the frame.

During the angular adjustment of a sash the following action takes place. The slides, remain stationary by gripping and frictional, contact with the Weatherstrip members and by bearing against vertical stops of the frame. The latching members become detached, freeing the balance arms which in turn in combination with the pivot ends of the sash stiles start pulling the pivot blocks vertically toward the opposite ends of the slides until the sash is completely turned inside out. This arrangement of parting beads, slides, pivot blocks with flanges and balance arms in combination sets up a binding action between parting bead and pivot blocks, and slides and pivot blocks when downward or upward pressure is applied to the outer ends of the sashes and retards the vertical movement of the pivot blocks and holds the sashes in any angular position desired.

When installing and removing a sash from its "slides, with reference to Figure 17, place the sash in the frame with the pivot block and flange in normal position on the slide and flange runway on the one side of the window. Press the parting beads and slides back towards the jambs on both sides of the window until suflicient cleartime is available to allow the other pivot block and flange to enter their positions against the slide and between the slide and parting bead on the other side of the window. Theopposing pressure of the parting beads holds the pivot blocks in position. To remove reverse the operation. The slotted connection in the ends of a balance arm as in 95 Figure 14 allows a certain angular adjustment of a sash without vertically moving the pivoted end of the sash.
